Hi
Is *.PSD files a lossless image file like *.TIFF ?
Are there big differences between these two types of files format ?
Thanks
Carlos
It is lossless. It’s the native file for Photoshop. It’s not like a TIFF file because you can’t save a TIFF as a layered file. For instance: when you do any sort of creating in PS you don’t work on one layer. You work on multiple layers – maybe layer 1 is your background, layer 2 could be a text layer, etc.
Saving in TIFF or JPG or GIF will flatten the image so that when you open it you will see only one uneditable layer. A PSD file is what you want to save when you need a file that you can edit individual layers.
Whenever I am working on something I save the PSD as Image Working File.psd or whatever the name will be but I always add WORKING FILE at the end so that I know what it is.
If you work in Illustrator you can export that file to PSD. It will flatten some layers though.
